Simple Shell Script

Hello Friends,

I am writing a shell script which will grab a file if it exists and copies it to another folder and will append with current date. I have written but gives me error, plz help:
--------------------------------------------

#!/usr/bin/sh

source=/home/dev4rice/naveen/test1
target=/home/dev4rice/naveen/test2
file_name=$source/text.txt
target_file=$target/text.txt

if [-f $file_name]

cp $source/text.txt $target

chmod $target/text.txt 777
fi
cp $target_file $target_file`date +%y%m%d`

--------------------------------------------------

Error I am getting is :

./copy_file.sh[8]: 0403-057 Syntax error at line 14 : `fi' is not expected.

if [-f $file_name]; then

cp $source/text.txt $target

chmod 777 $target/text.txt
fi

I fixed as per your suggestions but still getting following error -

$ ./copy_file.sh
./copy_file.sh[8]: [-f: not found.
cp: /home/dev4rice/naveen/test2/text.txt: A file or directory in the path name does not exist.

#!/usr/bin/sh

source=/home/dev4rice/naveen/test1
target=/home/dev4rice/naveen/test2
file_name=$source/text.txt
target_file=$target/text.txt

if [-f $file_name];
then

mv $file_name $target

chmod 777 $target/text.txt 
fi
cp $target_file $target_file`date +%y%m%d`

pay attention to spaces:

if [ -f $file_name ]; then
  cp $source/text.txt $target
  chmod 777 $target/text.txt
fi

Its working now thanks

#!/usr/bin/sh

source=/home/dev4rice/naveen/test1
target=/home/dev4rice/naveen/test2
file_name=$source/text.txt
target_file=$target/text.txt



if [ -e $file_name ];

then

cp $file_name $target

chmod 777 $target/text.txt 

fi

cp $target_file $target/text_`date +%m%d%Y`.txt
